Patent CA-2018948-A1 (CA)
Title: Tool for machining workpieces
Inventor: GUINAND PIERRE
IPC: B23B27/14
Filed: 1990-06-13
Abstract: INVENTOR:   PIERRE GUINAND          INVENTION:  TOOL FOR MACHINING WORKPIECES                   ABSTRACT OF THE DISCLOSURE          For cutting hard-metal workpieces there is used a cutting tip comprising a hard-metal support and a layer applied thereto, e.g. by sintering.  A cubic boron nitride is used for the layer applied to the hard-metal support.  The mounting of such a cutting tip at a cutter shank causes problems.  When the cutting tip is brazed or welded on to the cutter shank there is the risk that, due to heating, the structure of the layer applied to the hard-metal support changes or that cracks occur due to thermal stress.  In order to preclude such change of structure or the formation of cracks, the cutting tip can be affixed to the cutter shank by screws.  At the cutter shank there is provided a slot in which the cutting tip is located and clamped between side walls or the slot by means of fastening screws.

IPC: B22D41/22
Filed: 1990-07-17
Abstract: Abstract of the Disclosure Apparatus is disclosed for confining a protective shroud in a region surrounding a stream of molten metal being top poured into an ingot mold from a ladle.   The apparatus includes a generally cylindrical windscreen member attached to the bottom of the ladle with its axis generally vertical and concentric with a tap hole in the bottom of the ladle through which molten metal flows when released by a valve.  An apertured cover plate is telescopically fitted over the windscreen.  The cover plate is supported by a wire harness assembly coupled to the underside of the ladle for suspending the cover plate in a hanging relationship beneath the ladle.  Lift line apparatus is provided for changing the elevation of the cover plate with respect to the ladle and windscreen in response to changes in the application of tension to the lift line.  The cover plate is configured to rest upon, and form a seal with, the upper rim of the ingot when the cover plate is lowered while positioned above and aligned with the ingot.  The windscreen and cover plate are made from a fibrous ceramic low density material to facilitate manual handling.                                           A4->R4

Title: Congestion avoidance in high-speed network carrying bursty traffic
Inventor: GOLDSTEIN FRED R
IPC: H04L12/56
Filed: 1991-03-21
Abstract: CONGESTION AVOIDANCE IN HIGH-SPEED              NETWORK CARRYING BURSTY TRAFFIC     ABSTRACT OF THE DISCLOSURE     A data communication network subject to bursty traffic employs a bandwidth allocation scheme to avoid congestion.          When a source node has a burst of traffic to send, it first sends a bandwidth request message through the network from source to destination.   At each intermediate node,  this bandwidth request is examined and the node determines how much of the requested traffic level it will be able to support at a time in the future of one round-trip interval hence, and this node either grants the request or marks down the request to a level that it can support, then passes it on.  When the request reaches the destination, it is returned along the same path  to  the  source,  and  the  source  then  employs  the marked-down allocation to select the rate used to send the burst of data.  The allocation for this source node remains in effect for a limited time, depending upon the amount of data to be sent in the burst, then returns to a "residual" level.
